AR10 heavy buffer

[Blalock]

Would a 10 oz heavy buffer help a short cycling gun or would it make it worse?

Did you check other things? Like gas block aligned properly, no leaks in gas tube and ammo being used? Maybe your issue with short stroking.

Not my rifle I posted for a friend. He only has short strokes with lighter bullets like 147. Once he moves to 168 or 180 no problems.

A heavier buffer would be needed if the gun was over gassed; since it is short stroking, it sounds like the bolt isn't getting enough gas or the loads are underpowered.

Does he have a true Armalite AR10 or is it a LR308? Either should cycle 147gr NATO with out an issue.

op: ask your friend if he's shooting reloads w/ the 147 gr.

Yes he was, ultramax but also 147gr Radway Green surplus.
